Hi
What version of Camel and Spring are you using?
Can you try with latest code from trunk?
And you can enable TRACE logging at org.apache.camel.component.bean
that may help to identify what could be wrong.
And can you create a small unit test demonstrating this issue and
create a JIRA ticket and add it there.
